In the vacuum cleaner cyclone dust collector configured as described above, dirt and the like are introduced into the cyclone body 20 in a diagonal direction through the first connecting pipe 21 together with the suction air by the suction force generated at the suction port of the cleaner. As a result, the air is lowered to the bottom of the waste container 30 while forming a swirling air flow (see the solid arrow in FIG. 1). In this process, the dust and dirt contained in the air by centrifugal force are separated from the air and collected in the waste container 30.

Subsequently, the air flows toward the cleaner body through the micro-pores 42, the air outlet 24, and the second connecting pipe 22 of the grill member 40 by the airflow reversely moving up and down at the bottom surface of the waste container 30. Ejected (see dashed arrow in FIG. 1). At this time, a part of the dirt rising together with the air by the air flow rising from the waste container 30 is reflected by hitting the non-return plate 43, the direction of travel is converted to the swirling air flow, therefore, the dirt is again turned air flow Get caught up in. The dirt which cannot be separated from the upward airflow by the backflow prevention plate 43 is discharged together with the air through the micro-pores 42 of the grill member 40. At this time, the dirt larger than the size of the micro-pores 42 is caught by the swirling air flow again as the micro-holes 42 do not exit.

Therefore, it is necessary to periodically shake off dust and dirt that cling around the micro-pores 42 of the grill member 40. In the conventional cyclone dust collector, since the grill member 40 is coupled to the cyclone body 20, in order to remove dust and dirt accumulated on the grill member 40, first, the waste container 30 is replaced with a cyclone body ( 20, the grill member 40 is exposed and then brushed off by brush or hand. Therefore, there is a problem that the work is not only cumbersome but difficult, and also contaminates the surrounding environment while the dust is blown off during the dust and dirt.

The present invention has been made in view of the above problems, and by automatically rotating the dust and dirt sticking to the grill member while rotating by the swirling air flow generated in the cyclone dust collector prevents the flow path of the grill member is blocked by the dust. In addition, the object of the present invention is to provide a cyclone dust collector for a vacuum cleaner that does not need to perform a separate operation for dusting off the grill member.
